nobody explained better than you mate👍 1 question though. i have a 33 watt xiaomi charger. will it charge my laptop, if its slow then also i don't have any problem? my laptop charger rating is 65 watt = 19.5 v, 3.33 a. thanks
Thanks for your kind words! 😊 Using an underpowered might result in slow charging and also a risk of overheating the charger. In this case, it might not charge at all. I wouldn’t recommend it, but if you decide to test it, make sure to do so for a short period and monitor it closely.
hi quick update. i have bought redmi note 13 pro last week and a usb c female to dc adapter that supports 100 watts charging which i bought yesterday. but now my redmi's 67 watts charger when connected through this adapter is not charging my laptop. it blinking at a slow rate. pls tell what to do? should I return it back? @@simplymaker
My question is how the laptop will handshake with the charger the adapter doesn't have the data cables for the communication, a charge starts with 5v and then pumps more if the device supports it. I think that's the handshake part, it either works with data communication, or ir just uses the resistance response
There is no direct communication between the charger and the laptop. The PD to DC cable I recommend contains a circuit that senses the required voltage and handles the handshake and communication with the charger to ensure the correct voltage is delivered.
I wish I had found this video several hours ago when I first started researching this. Unfortunately, I need a 150w (19.5v x 7.7a) power supply and I'm having difficulty finding anything compatible. The connector type is a 5.5x2.5mm for a MSI GE62 2QF. Is that simply too high a wattage for this type of usb charging set-up?
Indeed, currently most charger can output at 20V 5A which might work for slower charging. But using it when the battery is low or during high CPU usage might be challenge. Moreover all the DC to PD adaptor in the market now only accept at 100W max.
@@simplymaker Oh well. I am planning a sustained bikepacking trip (several months to multiple years) and I didn't want to have to lug 3.5kg worth of computer equipment with me, nor do I want to buy a new laptop. I don't mind a slow charging speed, and I guess I'd have to avoid gaming on it with a 100w power supply, but I was reading that having too low a wattage supply can cause problems for a laptop and possibly damage it. Worst case scenario, my legs just get an extra work-out.
PD 3.1 should be able to deliver maximum of 240W. But I have no idea how easy is to get any equipment that supports this standard. Maybe getting spare laptop battery will work for you for now?
I have a Dell G15 laptop. The current charger is 240w, but I'm thinking about trying to charge it with a 100w power brick and a USB-C to DC adapter. Has anyone tested it to see if it works?
Thanks for the video it was a lot of help, i have a que though, can a 65W charger charge 65W power bank or does the charger need to be a bit higher wattage?
I'm glad you found the video helpful! To answer your question, a 65W charger should be fine for a 65W power bank. The main benefit of a higher watt PD charger is that it can deliver higher voltage to supported devices. In the case of a laptop, if the charger can't provide the required voltage, it won't work. For devices that need a specific charger, the recommended minimum wattage is usually specified in the manual. However, for general devices using a native PD port, it can adjust the voltage based on the input. The worst-case scenario is it will charge slower, but it will still work. A higher watt charger is also beneficial when using a multi-port charger to charge multiple devices at the same time. Just be careful when select the charger, as I mentioned in the video, the wattage advertised on multi-port chargers is usually the combined maximum wattage, not the single port output.
Thanks for video!) But not sere why you suggest to use max total power of laptop stricly even if your laptop eat 120W(on it max usage CPU + GPU) and you give him chanrger with correct voltage but less Amper(say 19.5v*3.2A(65W total)) it will work but just will required a lot more time for charge. For some laptop wich max power usage is upper then 200W it's only one way to use usb-c it accept less powerfull charger.
I'm sorry, if I made you misunderstand. I'd recommend using the info from the original laptop charger as a starting point to figure out the minimum power needed. It's totally fine to use a USB-C charger that can deliver more power than required. By the way, back when I made the video, even 100W chargers were big and pricey. So, I'd like to have something small and easy to carry around.
It's ok if it is PD adaptor. However, for a regular AC to DC power supply, I recommend using the one that came with your laptop. Using a power bank or adapter with a higher wattage (20V 5A = 100W) is generally safe for your laptop, as long as the voltage is within an acceptable range (19V vs. 20V). Your laptop will only draw the amount of power it needs (19V 3.42A = 65W) from the power source. it's also important to ensure that the connector and polarity are compatible. If in doubt, check your laptop's user manual or consult the manufacturer for confirmation.
Nice video Sir. Can you help me choose a good usb-c charger for my Lenovo P50, 170 watt on Ali Express. It still works great but the original adapter is dead.Thanks, greetings from the Netherlands.
@@erdantzer Thank you! 😊 After looking into it, I found that most single-port USB-C chargers top out at 140W, so unfortunately, I can’t recommend one that would fully meet your P50’s 170W requirement.
Out of curiosity, what happanes if you use a lower end charger? My laptop is 65w (@20v), but what happens if I use a usb charger that is lower voltage or wattage? For example, what if i use a charger thats only 45w@20v, a 20w@10v, or in an emercency, i use like a standard 5v2a(10w) charger? I assume it won't kill the laptop, there is probobly some protection circuit l, but would it charge (at all, even if only when off) or just slowely discharge; at all like mobile phones, or just decline to charge all together? I'm currious how windows and the hardware would react to that situation.

I think most laptop draws power from its battery even when plugged in. Regarding performance, have you checked the OS power management settings? They might prioritize maximum performance when charging but limit it on battery power. If your power bank can charge your laptop, it should perform similarly to being plugged into an outlet, though high-performance laptops might drain the battery faster.

In normal case, it should handle extra 0.5 volt but I cannot garantee that. To make sure, use multimeter to measure your fully charged laptop battery. I think it will be around 21v.
The solar panel output will vary depending on weather conditions, so it might not charge without sufficient sunlight. Additionally, you'll need a voltage regulator to convert the solar output to match your power bank's charging specifications.
